Blackberry Keyboard won't work

it wont connect, i dont even know what the LED lights on the keyboard mean. but its fully charged. i turn it on, try to connect with bluetooth and it wont connect. it used to work, now it doesnt. itll just give some sort of error message when i try to connect it

My keyboard has decided to stop working on me as well. At first the 'o' stopped working and then sometimes it would start working again and the 'a' wouldn't work. Then after about a week, the keyboard started getting worse and not even responding at all, sometimes if I click all the buttons on the keyboard for a while, the screen will comeback on and the keyboard will work for about 2 minutes and then stop responding. The trackball still works but the buttons around it sometimes don't. I don't know if it's the keyboard or the system, help?
